Patent JP-H10104296-A (JP)
Title: Microcomputer control instrument
Inventor: FURUTA NAOHIRO
IPC: G06F11/22
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To normally operate an instrument without causing the abnormal operation of an additional circuit even when an additional circuit connecting terminal is short-circuited with a terminal adjacent thereto by dust by connecting a receiving terminal to an input port, and substantially laying the receiving terminal into released state in the state where no external device is connected to a communication connector. SOLUTION: In general use, a communication connector 3 is laid in non-used state without connecting an external device thereto. Since the input port 6 of a microcomputer 1 connected to a receiving terminal 13 has a high input impedance, the receiving terminal 13 is substantially laid in released state. Thus, even if the receiving terminal 13 is short-circuited with an additional circuit connecting terminal 15 by dust, any signal from the communication connector 3 side is never imparted to the input port 9 of a watch dog circuit 2 connected to the additional circuit connecting terminal 15. Therefore, the watch dog circuit 2 is normally operated according to only the output from the watch dog output port 7 of the microcomputer 1.

Title: Device for transferring data
Inventor: SAKO KAZUYA
IPC: G06F13/00
Filed: 1987-10-16
Abstract: PURPOSE:To extremely improve the speed of a data transferring by instructing either a reading operation condition or a writing operation condition according to the level of a signal to be outputted from a control device for a processor. CONSTITUTION:During a period in which a control signal R/the inverse of W is a high level, a logical product circuit 38 is selected. Namely, in order to execute the transferring of data, a lock signal to be outputted from an arithmetic and control unit 21 is counted by a binary counter 34 and outputted to decoders 35 and 36. During the period of a reading cycle, on a stage in which the decoder 36 is selected by the circuit 38 and the binary counter 34 counts 16 bits, the latch of the data to a buffer register 28 is executed. On the other hand, in a writing cycle, the signal R/the inverse of W is a low level and accordingly, the decoder 35 is selected by a logical product circuit 37. At such a time, when the counter 34 completes the counting operation of 40 bits, a latch control signal is outputted to the register 28. Thus, a data length to be needed for the transferring is reduced.

Title: Audio power amplifier
Inventor: YUKITA MASAHIRO
IPC: H03F1/02
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent a beat noise fault while avoiding a ground noise on a common reference potential by providing a high output while effectively utilizing a power supply voltage at a maximum by supplying a voltage, which is boosted by using a charge pump circuit to operate with a power supply potential as a reference, to a push side driver transistor. SOLUTION: A charge pump circuit 3 alternately turns on switching transistors M4 and M5 through a control circuit 5, charges a 1st capacitor C1 with a constant voltage Vr due to a constant voltage circuit 31, transfers the charging voltage to a 2nd capacitor C2 and charges it so that a potential Vch (Vcc+Vr') higher than a power supply potential Vcc can be taken out. Since the charge pump circuit 3 is operated not with a common reference potential GND but with the power supply potential Vcc as a reference, the generation of noises on the common reference potential GND with operating can be remarkably reduced. An audio circuit applies the boosted voltage Vch to the push side driver transistor of a push/pull output step as an operating voltage.

Title: Attachment of lead wire under pressure
Inventor: FUJISAWA MASAYUKI
IPC: H01R43/048
Filed: 1987-10-21
Abstract: PURPOSE:To make it possible to perform attachment of lead wires under pressure at a high reliability without producing buckling if a plurality of pressure attachment terminals installed together are attached simultaneously under pressure by performing the pressure attachment through a first process of rolling the connecting members of each pressure attachment terminal into core wires and a second process of pressing the pressure attachment terminal rolled including the core wires by means of an upper die contacting only the upper half of the forward ends of it. CONSTITUTION:The processes of pressure attachment are composed of a first process and a second process; in the first process, core wires 4 of a lead wire are inserted into a U-shaped connecting member 3, and pressed by means of an upper die 1, so the forward ends of the connecting member 3 are curved to include the core wires 4 rolled in. In the second process, the forward ends of the connecting member 3 are further pressed to be rolled into the core wires 4 by means of an upper die 1' which contacts only the upper half of the forward ends of the pressure attachment terminal. Because the upper die 1' consists of only a part corresponding to the upper half of the pressure attachment terminal, a sufficient pressure can be applied without producing buckling of the connecting member 3. A plurality of pressure attachment terminals installed together can thus be attached under pressure simul-taneously, thereby reliability of pressure attachment connection can be improved.
